Well, I had left "prior depreciation" blank initially, and then I got no 8829 form at all (only the worksheet), and therefore, no deduction. I went back through the process with a TurboTax advisor, and that's when we caught this empty box, so they had me add the depreciation from last year, which was 1947, as I mentioned. Only then, did the system generate the 8829 form with accompanying deduction for this year. So, leaving the "prior depreciation" box blank did not help me, I'm afraid.
I am not sure what "tables" you were referring to. I did not use any myself. The percentage I mentioned, 2.5641%, was automatically generated by the online TurboTax system and automatically appeared on the 8829 the system generated. Looking at the IRS website, however, that percentage does appear in a very simple chart on the page I referred to in one of my last posts under their discussion of Line 42. However, I did not enter the percentage myself; the online system did.
