A quit claim deed is not a tax document.  It shows ownership of property.  It would not be entered on your tax return.  Can you clarify why you are wanting to enter it on your tax return?

I make payments each month, and interest was about $1600 for the year 2020.

Contract for deed is probably the correct term. 

if you don't get a 1098, 

enter your interest paid under "interest not reported on a 1098"

Schedule A line 8b

click on "The seller is financing this loan and I didn't receive a 1098."
