Cannot file - get this message: TurboTax Business is not ready to process Tax Year 2023 for this return. Turbotax year 2023 transmissions are not available.

Correct ..GA e-file forms are not supposed to be ready until 1 March...though its' really likely to be 2 March in spite of the table...so another week,

State Forms Availability for TurboTax Business (intuit.com)

GA partnership just did an update but I'm still getting the not ready message.  Is this correct?

Don't know....I don't have any GA forms myself..

BUT...you might need to go thru the GA Q&A form start to finish again in case there are some other questions that are needed to be answered after the update.

IF you look at the GA forms availability in the link I posted in the reply above, yours you'll see that some partnership forms are not expected to be ready until 8 March ...you can check that yourself at any time.

Thanks.  I did look it up but they keep pushing the date back, it was supposed to be yesterday, March 1st.  The 8th is just too close to the March 15th deadline.  Since the missing forms are the e-file forms, I'll just print it out and mail them.
