Going through removal proceedings without an attorney is reckless. Given advice about removal proceedings remotely that it without having the entire record reviewed first, would be reckless as well.

You need to notify USCIS that he is removal proceedings so they can expedite the I-130 in 60 days. You cannot file the I-485 with USCIS since he is in court in removal proceedings and only the court has jurisdiction. You really need to hire competent counsel to help you with this, since this is not something you can handle on your own.
When filing with the USCIS a USC and immigrant spouse may file the I-130 and the I-485 at the same time. However, in removal proceedings the I-130 must first be approved by the USCIS and the I-485 is filed with the court.
I strongly advise you retain an experienced immigration attorney to assist you. Your spouse is one step away from deportation. Should you have filed the I-485 you would not have been successful and may have lost over $1000.00.
