After you file

I got a letter I missed my husband marketplace ins. So I had received a 1095-A and form 8962 and it suggested mailing and that was mailed 03/11/20 and today is 6/22/20 and it keeps saying nothing is in their computers. One associate said maybe I should try refiling duetdue to so many doors that had closed due to covid19 so can I  refile they said which ever comes first would be honored the other will cancel out if found. 8962 and 1095-A where I originally filed my taxes and that was turbo tax. This was my first year filing our taxes solo
