After filing my federal tax returns, after struggling to figure out the state ones, I decided to use TurboTax to finish it up. However, because I already filed my federal taxes, the state taxes got rejected with the federal ones. If I can’t file them separately, is there anything I can do to not have them be rejected?
Since a federal tax return has already been filed and accepted by the IRS, you cannot e-file another federal tax return. Nor can you e-file the state tax return because the federal return has not been e-filed using TurboTax. The state tax return can only be printed and mailed.
See this TurboTax support FAQ for how to print a tax return for mailing when using the online editions - https://ttlc.intuit.com/turbotax-support/en-us/help-article/printers-printing/print-mail-return-turbotax-online/L5bwuqXGy_US_en_US?uid=lva23xc9
You can only efile state if Federal was efiled and accepted from the same account. So you will have to print and mail state.
If you didn't use Turbo Tax for federal, There is a way but you first have to fill in the federal and pay for federal for it to flow to state. You will have to mail state. See,
