TT Desktop Premier (windows) does NOT allow you to enter pass-through entity tax withholding anywhere during the walkthrough for RI (NR) State filers. And even on the FORMS option, the appropriate line on the Tax Payments worksheet does not allow an entry (K-1), you must put it under "other" withholding (Even though there is a line for K-1 withholding), and even when you put it there, it does not carryover to the "payments and credits" section of the 1040NR, so you have to go enter it there also manually.
Also, on the same RI walkthrough, there is NO option for entering AGI modifications (increase/decrease) for items like bonus depreciation add backs or credits.
TT consistently fails in supporting Business and/or K-1 filers as it pertains to STATE forms. Basically, to get an accurate State return you need to use the FORMS feature for most details, and even then you have to use workarounds. What's the point of having a walkthrough if it leaves you stranded? At the end of the day, what TT is actually "selling" is the walkthrough.. you can get the forms anywhere. So why am I paying TT when I have to do it manually in the end anyway? I'm sure it's because K-1 filers are not TT's "Bread and Butter" user, so our needs go to the bottom of the list. This will be my last year using TT .
