Based on this site, https://ttlc.intuit.com/community/tax-topics/help/how-do-i-change-my-payment-date/00/1331857
I do not think TurboTax is going to change the software to allow a direct debit tax payment after April 15. It says just change to check.
I have NOT filed yet and it will not accept a Choose Direct Date after April 15, 2020. I will change to pay by check and mail it in at my convenience or via IRS website.
