Thanks @DanaB27!
For the first payment for the underpayment penalty, can you check the attachment to see if these are the correct reason and options to select on directpay.irs.gov website?
Just to confirm that I could do the following step-by-step?
1. Select "Pay by check" and e-file the personal tax return via Turbotax
2. Use directpay.irs.gov website to pay the first payment for the underpayment penalty with the reason and options selected in the attachment
3. Pay the second payment for the tax due before the deadline at 4/15/2023
I really appreciate your help, @DanaB27!
