K-1 and 1099-B how to enter properly so nothing is duplicated

On the advice of a friend, I started experimenting with investing via M1 Finance as I could do fractional shares which made it affordable for me. So I now have a 1099-B from M1 listing all the companies I invested in and some K-1's from various L.P.s (if only I'd known how much of a pain these L.P.s are to deal with when it comes to taxes I would have never touched them but I guess we live and learn) and I'm wondering how to properly enter all the info so nothing is duplicated.


The amounts are very small and I'm not sure it will even make a difference in my taxes but I still want to get it done correctly. I've looked around on the forums here but can't understand what needs to be done and the one instruction I could find that I could understand, TurboTax wouldn't let me do it.


So I was wondering if someone can help me and walk me through step-by-step? Please? If so I'd really appreciate it!


Here's an example using the info for BSM, one of the L.P.s, from my M1 1099-B and the info from the K-1 they sent, in case that helps.

K-1 and 1099-B how to enter properly so nothing is duplicated

If you have a K-1 and a 1099-B for the same items and amounts you have two options.


  • Enter the information from the K-1 and do not enter the 1099-B information.
  • Enter the information from the 1099-B and do not enter the K-1 information.

Either of the methods will enter your information without any duplication.

Thank you for the info.


Seeing as the K-1 has some additional information that the 1099-B does not, can I simply delete the entries pertaining to Black Stone Minerals, L.P. from the 1099-B that was entered or will that cause problems?

Yes, you can delete the duplicated details from Form 1099-B. The problem is caused by the duplicate information received and entering it in both places. It is appropriate to enter it as you suggested, through the Schedule K-1 input.
