I refinanced my mortgage and have a question on how much of the interest can be claimed as an itemized deduction.

In  October, 2019 I refinanced my mortgage.  The new mortgage amount was supposed to be only for the amount of the original mortgage balance that I still owed, but the lender's calculation of this figure was incorrect.  After the pay-off on the refinance, the original lender sent a check to me in the amount of $2943 for excess mortage payments.  Do I have to treat the $2943 as pulling out money from my refinance and therefore not  taking a deduction for the full mortgage interest amount listed on the 1098 from the refinanced lender (who in turn immediately sold it to another institution)?

No, you do  report your payment you received for excess mortgage payments in any manner toward your mortgage interest.  Your payment you received is simply a reimbursement for a mortgage payment you made that was not captured by the title company at the time of closing.
