My taxes keep getting rejected. I downloaded the IRS transcript and put in the exact number, it's still getting rejected. Why?

I downloaded my paperwork from Jackson Hewitt in November 2020 and my AGI says its 33k, I downloaded it last week and it says its 32k. I download the IRS return transcript and its the 33k. This is my third time trying to submit this years taxes, I've tried two other times with the 33 and 32 numbers and they say its still wrong.

One, why would my AGI change and without notice on tax paperwork from last year?

Two, what do I do? My AGI is exactly the same as it should be (the 33k) with the IRS paperwork.
