Get your taxes done using TurboTax

Ok, so I now understand that I need to fill out line 4a or 4b and not both. 2019 was the first year so 4a should be filled in. 4b has a 0 and turbotax will not let me change it and will not let me file with a value there.

 

I tried deleting the whole form, but I don't see how to get there via the step by step.  So I re-added the form.  I seems like the IRA contributions from previous years should be entered on line 3 which refers to a a Schedule k-1.  But when I click on the magnifying glass and pick source, I get "Add Sch K-1 Partnership Additional Info 1"  What?

Can I just fill in 4a, print out my taxes, send in the paper and request a refund on filing from turbo tax?  Is that the best plan?
