Schedule K-1: TurboTax creates Form 1120S instead of Form 1065

There are different entry areas for each type of K-1 (Parternship/1065, S-corp/1120S,and Trust/Estate (1041).  Return to the K-1 entry screen and be sure to select that you are entering one for a 1065.  It should look similar to this:

If you're trying to prepare the 1065 return that issues the K-1 (and not trying to enter K-1 data onto your personal tax return, or have any other questions, you can return to this thread and ask us without any limitations on characters. 

Thanks @SusanY1 for the quick response. I am using the desktop edition.

I did enter the Schedule K-1 as a Partnership/LLC. 

I think this is a bug in TurboTax. I went ahead and filled out bogus information for the "S Corporation" it was asking me about, then deleted the Form 1120S, and the notification went away. But it keeps coming back.

There may be another form related to the entry you deleted that remains in your return. You can check this using Forms Mode in TurboTax for Desktop.

1. Open your return and click the Forms icon in the TurboTax header. 
2. In the list of Forms in My Return on the left, scroll down and look for any form than includes "K-1 S Corp" or "K1S." 
3. Click the form name to open it in the large window. 
4. If the form is related to the K-1 you deleted, click the "Delete Form" button at the bottom of the form and confirm. 
5. Click Step-by-Step in the header to return to the main screens.
6. Now run SmartCheck again to see if the error has been resolved.
