The IRS website stated that in late March, the IRS changed the AGI to include unemployment but deducted it from the MAGI to exclude it for testing whether it was taxable or not based on your gross income. When I went into 2020 return, the program updated since Turbo tax must have known this, and carried forward the corrected AGI. But the actual return I submitted I used the AGI on the printed efiled return. Not sure why Turbo Tax didn't instruct us to not use line 8 of our 1040 return if it was filed before March, since the AGI was changed by the IRS.
At any rate, the return was accepted by using the amount that Turbo Tax populated the prior year field, which added in the unemployment to the AGI.
