I appear to be in the same situation, because that's the only reason in the list that makes sense to me on blocking my e-file when I tried this morning (30JAN2024). I have the 1040-SR, Schedule 1 for the 1040, Schedule C, Form 8995, and the 1099-R forms you mentioned. Those are my only forms. I haven't been able to find the info online as to whether the forms are final yet, so was planning on talking to TT support when they open. I've used TurboTax for a number of years and never run into this issue before either.
