So I was having the same issue. I kepted getting rejected. The last rejection they advised that my IP PIN was wrong. The IRS sent documentation back in Dec or Jan with a new pin. Unfortunately I could not find mine. The good news is that you can reset it>> here Retrieve Your IP PIN | Internal Revenue Service (irs.gov). I reset mine, entered that number and the correct AGI and it was accepted. Please note this is not you signature pin(5 digits), it's and identity pin(6 digits).
