I too am running into the same problem. I efiled my federal return on 3/10/21, it was accepted by the IRS on the 11th. Now, I'm trying to efile the Ohio state tax return and it won't let me file. It keeps telling me I have to go back a screen and select to efile the Federal tax too. That won't work because the screen back there shows that the Federal tax has already been filed and accepted. There is no option to select Federal even if I wanted to. I am using Turbo Tax Deluxe version installed on my computer not the online version.
