I filed 2019 return via Turbo tax on 3/26/20. I was advised via email (and ongoing status) from TT that it was accepted. IRS says otherwise and must refile it. How?

Have not had satisfactory response from TT.  I owe and cannot set up payment plan without accepted tax return.   Must refile.  TT refers to IRS "Where's My Refund."  Not helpful.
