I have an old K1 form from last year. How do I delete it from the pc version. TurboTax has me in a loop to fill it out

On the desktop version of TurboTax, click on Forms on the top right of your screen and you will see a list of forms on the left half of your screen. On that list, locate the old K-1 and all the related worksheets. Delete these forms and your K-1 will be gone.
