After you file
Patricia,
Concerning "1) Adding Section 754 Depreciation to Form 1065 p405 Line 13(d)C, Code W, adds an amount to Line 13 of the Federal K-1s.", I just want to point out that according to the IRS, Section 754 Depreciation under sec 743b is supposed to be reported under Code "V", not "W". And, that is how I reported it.
"The partnership would allocate depreciation expense related to the section 743(b) adjustment of $1,600 depreciation for Partner A and would report that expense on Schedule K-1 (Form 1065), line 13, code V."
I will also note that starting in 2021, TTB does provide a new checkbox to facilitate "743b" adjustments, which if selected, does allocate the adj to Code V. However, it does not provide the same option at the state level.
Thus, I suspect that TTB calculated 3804 QNI and PTE tax if one checks the 754 box, but not the 743b box.
However, having updated TTB today, the 3804 Wks is now making the correct calculation and includes the line 13 Code V deduction! So all good on that count.
