Reporting distributions from an inherited annuity that has a cost basis

I input my 1099-R distribution from an inherited  Non Qualified Annuity and checked the Non Qualified Annuity box.  However the following TT questions appear to refer to IRAs and RMDs.   Although I have to take $ out each year, I don't believe my distribution is a RMD.  Also, unlike 2023, there doesn't appear to be a place to input my cost basis.    Am I imputing my annuity in the wrong way??  Many thanks for all your help!!
