Getting the same error "tax year 2023 transmissions are not available..." Agree very confusing about the whole form 8453-PE not being supported, but not being the issue after reading the posts. So, is waiting till 3/8 the current recommendation? Is that coming from TT? Very very frustrating. How something that was working (I filed last year with no issues, this form 8453-PE was not required though) is not working anymore? TT is going backwards
