I did my taxes w/ TurboTax, submitted/paid on April 15, 2019; then noticed in my bank account the tax payment was never withdrawn, checked my TurboTax account found error

in my TurboTax account I found that at some point an error occurred and TurboTax used the wrong AGI from prior year, so my tax files were rejected; had to resubmit and re-file with manually entered AGI; will now have penalty and interest for late payment, so TurboTax should pay this.  How do I contact TurboTax customer service to take care of this?
