Dought & clear, - He came from Egypt to Jeddah for work during Hajj season, then he was given permission todo Hajj, so he entered ihram from Jeddah

I am from Egypt, and I went to Jeddah for work during Hajj season.
After spending twenty days in Jeddah my work ended, and I was given
permission to do Hajj, so I intended to do Hajj from that time, and I
entered ihram for 'Umrah from Jeddah, intending to do Hajj tamattu'
(in which one enters ihram for 'Umrah, exits ihram after 'Umrah, then
enters ihram again for Hajj on 8th Dhu'l-Hijjah). Is this correct, or
do I have to go back to the miqaat of the people of Egypt?
Praise be to Allah.
If a person wants to do Hajj or 'Umrah, and he is outside the miqaat
boundary, he has to enter ihram from the miqaat. However, if his place
of residence is within the miqaat boundary, such as the people of
Jedah, then he may enter ihram from his place of residence, because of
the report narrated by al-Bukhaari (1524) and Muslim (1181) from Ibn
'Abbaas (may Allah be pleased with him) who said: The Prophet
(blessings and peace of Allah be upon him) defined the miqaat of the
people of Madinah as Dhu'l-Hulayfah; that of the people of Shaam
(Syria) as al-Juhfah; that of the people of Najd as Qarn al-Manaazil;
and that of the people of Yemen as Yalamlam. They are for them and for
others who come through them with the intention of performing Hajj and
'Umrah; and whoever is living within these boundaries (can enter
ihram) from the place where he starts, and the people of Makkah can
enter ihram from Makkah.
The words of the Prophet (blessings and peace of Allah be upon him),
"and whoever is living within those boundaries (can enter ihram) from
the place he starts" mean: he can enter ihram from the place where he
is. As you did not form the intention to do Hajj until after you
finished your work, at which time you were in Jeddah, then you may
enter ihram from the place where you are, and you do not have to go to
the miqaat.
Shaykh Ibn 'Uthaymeen (may Allah have mercy on him) was asked: I was
sent (to Makkah) by my company during Hajj season and I travelled with
the group as far as Mina, then I decided to ask my work for permission
to perform Hajj. Should I go to the miqaat and enter ihram from there,
or can I enter ihram from the place where I am?
He replied: You can enter ihram for Hajj from the place where you are,
because when you passed the miqaat, you did not know whether you would
be given permission or not, so you had not decided to do Hajj. So for
example, if they gave you permission in Mina, then enter ihram from
Mina; if they gave you permission in 'Arafah, enter ihram from
'Arafah.

He was also asked: In sha Allah, I am intending to do 'umrah on the
day of Hajj, and I am assigned to do some tasks during Hajj season. He
said: If my work allows me, and it is most likely that work will not
say no. But we say there is a 10% chance that they may say no, as a
precaution. He has passed the miqaat now; does he have to go back in
order to enter ihram from the miqaat?
He replied: No. If the man has been given some tasks to do and does
not know whether he will be given permission or not, he does not have
to enter ihram from the miqaat. Then if he is given permission, he may
enter ihram from the place in which he was given permission.

And Allah knows best.
