This frustrated me for several hours. You can't update the Form, but you can update the Form Worksheet.
Go to View (at the top of the Screen)
Select Forms
Forms Drop Down Menu Appears
Go to Forms
Select Open Forms
From the Forms in My Return on the left side of the screen, Open the 8915-T Wks (Worksheet) form
At the top of the Worksheet, UNCHECK the B option (Coronavirus-related distributions...)
This will automatically get rid of the 8915-T Form!
Feel free to holler back if you can't figure this out. I even took out the 401K entry and re-added it, before I figured this out.
