This excuse-making in these responses is pretty frustrating. I'm having the same problem - about to file 2025 and turbotax is showing a 2024 AGI that is $9,000 higher than the AGI on my filed form. I logged into my IRS account and right there on the IRS site it shows my 2024 AGI being the exact same as what I filed last year. No amendments, no rounding of pennies, and most importantly no links for me to drill in and figure out where turbotax is getting this number that is too high by $9k!
Update several hours later: I found the discrepancy. I started an amended 2024 return to poke around and compare with my original filed PDF. I sold a rental property in 2025 (45 days of use) and my 2024 data is now showing 75 days of use in 2024, while the filed form correctly has 366 days of use. Using 75 days lowers 2024 depreciation by $9k, increasing AGI by the same amount. I edited the days of use to "full year", but the wrong depreciation isn't updating. Either way... Why did my 2024 data change? Why is this different value being pulled into my 2025 process as the filed 2024 AGI for identification purposes? Given that my 2024 data has a too-low depreciation, why is the 2025 sale showing the correct total lifetime depreciation (compared to my hand-calculated value)? Note, I never edited 2024 previously and definitely never filed an amended return.
