Thank you for replying.  I might be asking the question incorrectly.  I've been reporting the 743(b) step up in basis correctly each year and specially allocating it to the applicable member.  Last year I neglected to make the adjustment to tax basis.  It's only about $1K each year that is specially allocated.  This is my only client with a 743(b).  I'm trying to report it correctly (tax basis) for 2021.  Here's what I did...I just don't know if it's correct:

1. Increased the beginning capital account in the M-2 screen by the prior specially allocated depr  (and adjusted the applicable member's beginning balance) and reduced the beginning A/D on the BS by the same amount.

2.  Lacerte automatically puts the cy specially allocated depr on line 4 of the M-2.

Should the cy specially allocated depr go in Box 13, code V?  If so, how do I do that?

How do I get code U to print in Box 20 and enter the remaining specially allocated depreciation?

Any assistance would be much appreciated!

Thank you!
