No I haven't heard this. You can file your return using your 1099R information. I am not aware of any IRS restriction.
Perhaps you need a 8606 form that will not be ready for e-fileing until 2/12 (estimated).
No, the answer didn't help. Here's what's happening
1 I open Turbo tax. I've been a user since about 2012
2 It checks for updates and apparently finds none
3 A popup says system.runtime.serialization.serializationexception.typr is not resolved for member
4 I check ok box and proceed
5 takes longer than usual to load my return (it does know my input from last year, etc)
6 When I try to input 2019 1099R I get the same message that says IRS is not ready for 1099R input, and it is expected to be ready by 1/21/2020.
Elsewhere Turbo tax tells me I can download a patch TurboTax 2019 Individual-R15.2 to manually update. also says there are no manual updates for state software. I'm 69 years old and prefer a tax program that does its own updating, but I guess I'll have to try the download unless I get a better answer.
