I appreciate everyone's concern. Maybe I can be more clear about what I'm now asking.
I've already learned a few things. TTSE won't do Form 1065. I would need to use TT Business for the Form 1065. But TT Business won't do personal taxes, so I'd also need TT SE. But TTSE won't help me plan for 2019 personal taxes yet because it still presumes I'm doing my 2018 taxes.
I'm now trying to discern if there's anything I can do now to investigate how either of the TT products/services would work for me for 2019. If anyone has any suggestions, I'm all ears.
