Can I safely delete forms 6252 from 7 years ago?

[JeffSPL311]

I did some installment sales  7 years ago, and I used Form 6252. Ever since then, TurboTax has imported these when I start my new year. I still have them in my forms list for this year. Only this year the form has been updated and it is now "missing information", which I have no idea how to correctly provide. Thus, can I simply delete the forms? I don't know how they are still relevant 7 years later, but I just wanted to double check before I axe them.

If your installment sale was completed before 2019 (e.g., ALL of the installments were completed before tax year 2019), you can delete the form. Here's how:

1. Open or continue your return in TurboTax.
2. In the left menu, select Tax Tools and then Tools.
3. In the pop-up window Tool Center, choose Delete a form.
4. Select Delete next to the form/schedule/worksheet in the list and follow the instructions.
