I have a rental home that I purchased in 1992. On my form 4562 the UBIA total was $68,999 (home itself was 66,000 + $1,999 (furnace placed in service in 2004) + $1,000(garage roof in 2004). My last two tax returns (2018 &2019) showed that UBIA amount ($68,999) on my "QBI component worksheet" in the middle 5 column section where it asks for the Business name, tax ID, QBI, W2 wages and then the UBIA. That UBIA amount $68,999 also showed on the "Smart Worksheet for Schedule E" under the QBI deduction smart worksheet line J 1. Now for my question, for tax season 2020, the UBIA amount is showing substantially different (less) than the previous two years. On those two worksheets it is $2,999, which coincidently would be the $1,999 (furnace) and $1,000 (garage roof) amounts added together. Why would the homes UBIA of $66,000 have fallen off? Does it have something to do with the depreciation?
