Using turbo tax free edition this year. Need to delete a K-1 Partnership. Can see where to access My account/ delete form.

It sounds like a K-1P was inadvertently created.  

To delete any of the forms in your federal or state return, please follow these steps:

TurboTax Online

1. While in your return, click My Account (in the blue bar at the top of the screen).  
2. Click on Tools.
3. Under "Other helpful links" click on Delete a form. 
4. Click Delete next to the appropriate form or schedule and follow the onscreen instructions. 
5. Once you have finished deleting the desired form(s) click the Continue with My Return box (in the lower right of your screen).

TurboTax Desktop

1. Go into Forms Mode by clicking on the Forms icon in the top right of the blue bar.  
2. In the Forms in My Return list on the left, double-click on the form you wish to open and delete.  [In this case the 1040X.] 
3. Click on the Delete Form box at the bottom of the screen.
4. To return to the interview, click on the Step-By-Step icon in the top right of the blue bar

Please see the FAQ below for directions on removing a K1.
