Form 3115 unreported depreciation > 50,000

[51pop]

Rental property sold 2024 unreported depreciation since 2008 > 50,000.  Line 28, how do I handle the entry? I would like to take it all as a 481a adjustment in 2024 since I will not have schedule E next year.

Unreported depreciation amount on page 4 part 1V line 26 would be negative number, right?

[Hi Palms]

Yes, negative adjustment. 

Don't forget to attach a sheet showing your calculations.

Can I take all 51K in 2024? What box to check on 3115 line 28? 
plan B : I can amend 2023 return take depreciation, then the amount for 3115 would be < 50,000K

[Hi Palms]

You can take the total $51k catchup in 2024.

The box on Line 28 is for positive adjustments (you're making a negative one) so it's not applicable.
