Thank you for this reply. Two things: the filing instructions do say that I have to mail a check. That was not at all clear when I was filing. Now my payment will be late. Sigh. Also, I was expecting to get an email reply to this request and did not know that I had to sign back into Turbotax to see this reply, so I waited a week for no reason. Double sigh. Thanks for the definitive answer, anyway.
