Deductions & credits

This is the 3rd year I have used TT to file my return. I imported last year's return. The depreciation amount is wrong in TT and I have not been able to correct it. I am not sure if I have one of the imput's wrong but here is my data. 

Purchase date 05/24/1999, purchase price 108,000 excluding land. Land 27,000

Date placed in service 08/01/2018, accumulative depreciation up to and including 2022 is 17,347 since I began to depreciate the house. 

Using 27.5 SL the yearly depreciation should be 3,927. TT is telling me the estimated depreciation is 2,904. 

Any thoughts on the discrepancy and how to correct it? 

Thanks
