Submitting my Business tax and the e-file came back with an error on the Federal taxes. TurboTax mentions under description of the error that "if the signature option "binary attachment 8453 signature doc" is selected then a binary attachment must be present"
Under what needs to be done it asks me to add a pdf attachment (not sure how) of form 8453 to my return with the description "8453 signature doc" then resubmit for e-filing.
