I sold an MLP and entered all the information regarding sale. However, tt is not picking up the passive losses that have accumulated. What am i doing wrong?

entering the sale on the 1099-B doesn't do anything regarding freeing up those suspended losses.  you must indicate final k-1. and then on the k-1 sales worksheet enter the required info. you donot enter the same info that was on the 1099-B otherwise you'll double up.  then on this worksheet enter as sales proceeds any income reported on the MLP sales schedule as ordinary income recapture - form 4797 line 10.  cost is 0 and the ordinary income is the same as the sales proceeds just entered on this worksheet. if done right form 4797 line 10 should reflect only the ordinary income while schedule D/form 8949 should reflect 1099-B sales proceeds and your tax basis which is not going to be the same as that on the 1099-B. this comes from the MLP sales schedule which you must compute.

There's a (very) long discussion here on how to enter the sale of an MLP:  https://ttlc.intuit.com/community/investments-and-rental-properties/discussion/how-i-report-the-sale...

But as stated in the previous reply, making sure that "Final K-1" is checked off is key to getting the suspended losses released.
