How do I remove a Schedule K-1 that was automatically carried over from the previous year without buying the premium version just for the deletion?

If you are using TurboTax Online, you could start in Premium, delete the K-1, then simply downgrade if you do not need the Premium version.

Follow these steps to downgrade to a different TurboTax Online product:

• Open your return if you haven't already.
• In the left menu, select Switch Products. 
• Select Downgrade.

This simple solution worked.  I was not aware of the option to temporarily upgrade.  Thank you!
