how much of a contribution did you make in total? until we know that hard to state whether the extra $1000 is within the limit. Are you single or family HSA?
$4500 is the limit for single / over 55. The additional $1000 should reduce your taxable income.
a 1095-c has nothing to do with an HSA. it just shows you had insurance coverage. nothing on it gets entered on the 1040. the other question is whom was covered by a high deductible plan. a HDHP is defined as one
with a deductible for 2019 of at least $1,350 for individuals and $2,700 for families with a max out-of-pocket $6750 single $13,500 family.
