Schedule E

I've had a rental property on schedule E for years. I sold the property at the beginning of 2020. When TT asked about number of days rented and number of days for personal use I entered zero for both. I then made the mistake of checking the box that it was not rented at all for the year. TT deleted the property altogether. I did not realize it was going to delete it.  I attempted to go "back" but the worksheet was gone. Is there anyway to recover it? I am not using the on line version, I have the CD. The only thing I can think of is to delete the tax return and start all over. Any suggestions?
