TurboTax only estimates the penalty. You can always choose to have TurboTax not add any penalty and let the IRS bill for any penalty the IRS determines, but since the Q1, Q2 and Q3 payment dates were all delayed until October 15, 2023, I would just indicate to TurboTax that the entire amount paid by October 15 was paid on April 15, 2023. If doing so eliminates the need for Form 2210, nothing about your payment-date entries will be apparent to the IRS.
