It is a bug, but I called Intuit support and was able to get the issued resolved and my 3rd E-file attempt was successful.
The rep explained that while many may be having similar issues - the fix is different based on the individual.
In my case - when we reviewed (via Step by Step) under PERSONAL > OTHER TAX SITUATIONS > ADDITIONAL TAX PAYMENTS > UNDERPAYMENT PENTALTIES...the tax due brought in from the 2017 listed an amount, but since we paid a penalty in 2017, the 2017 liability should have shown as zero. Once we changed that - the need for Form 2210 was removed.
