2020 Qualified Business Income deduction summary worksheet Line 9: Total REIT Dividends which transfers over to form 8895 Line 6 "Qualified REIT Dividends" and "PTP income and (loss). Data source states three different Sched K-1 's. I have no income from any K-1's and did not and will not receive any K-1's. The program did the same last year 2019 but I did not notice it.
I am seeing the same thing in the Windows desktop version of TT Premier. The Data Source shows coming from the K-1 as 0 but shows 18 on the Summary below. Not a REIT or PTP so it is obviously not transferring correctly. TurboTax needs to fix this bug. I'm going to override it to the get it right for me.
It's likely not a bug. If you have a Form 1099-DIV with a box 5 entry, that is where it is coming from. That box reports REIT dividends.
5smallhokies's response does not appear to be for certain. See other response above about 1099-DIV line 5 (Section 100A dividends).
