Deductions & credits

only your bank can't explain.  we have no access to their records.  A possibility is you're looking at the interest paid from the date the loan was taken out, the 1098 would only reflect 2020 interest paid.   another possibility is the statement includes interest that was to be paid in December but your check arrived in January.  These are only guess. when you call ask to speak to someone higher up at the bank. if they can't tell you ask them if you should inform your local newspapers about the problem the bank is having.  or report the bank to your local newspaper.
