I didn't receive my 1098s Mortgage Interest Statements for 2020 and I'm having difficulty grabbing hold of the recipients. Can I use 2019 1098s?

I'm reading that, if they didn't send me a 2020 1098, I can still  claim the mortgage interest I paid as a deduction on my taxes. How do I know what this mortgage interest is?

If your lender did not give you one,

there must be something on the internet that will give you an amortization schedule

based on your principal term and interest rate.

OR 

use Quicken loan calculator.

you must enter the correct loan begin date.
