Get your taxes done using TurboTax

@k1_learner19:  On your questions 1) The values on the K-1 box 9 and 17 don't affect the Sales Schedule.  Enter them on the K-1 and TT will handle it.  2)  TT will transfer the $400 to Form 4797.  But to be sure, I'd encourage you to just experiment a little.  Look at Form 4797 (in Forms mode) before and after completing this K-1.  You should see it increase by $400.  As for the 8949 Column G, TT won't automatically do that.  You need to figure out your capital gain/loss using the Sales Schedule, and then go to the 1099-B (I use Forms mode for this) and enter in a corrected basis (line 7a in your 1099-B will be what the broker provided; you can enter a revised number on 7b).  The number you use for the corrected basis is whatever value, when subtracted from your proceeds, gives you the right cap gain/loss.  Note that when you do this, you'll see an adjustment on 8949 Col G, which will be the difference between the broker provided cost and your revised cost.
