The Treasury Secretary announced that both the filing deadline and payment deadline would be extended to July 15. However, it will take some time to reprogram Turbotax and issue an update.

For late filing, no program change is required, since the program can e-file up until October 15. You will be past the regular deadline but the IRS won't penalize you. However, if you want an extension to October 15, you probably have to file the request form before the original April 15 deadline.
For late payment, Turbotax can't accept an electronic payment date after April 15, so select "I will pay be check" and then make your own payment arrangements by mailing a check or making an electronic payment at www.irs.gov/payments.
