Rejected return from 2019, is it too late to fix it?

When I did my return last year I was rejected due to not having an IP PIN, I never received the letter with my pin and I was unable to get it online so I could do nothing about it. This year I was able to receive my IP PIN from the IRS. Would it be possible for me to use this years IP PIN for my rejected 2019 return? and how would I go about re-filing a rejected 2019 return this late?
