On Form 926, how do I leave questions 2b and 2d blank? ProConnect filled them in, but they are not applicable.

The only way to call @INTUIT IS VIA https://proconnect.intuit.com/support/en-us/help-article/intuit-account-settings/contact-proconnect-tax-help/L031xWrR5_US_en_US?uid=l9zsd6y1

You can call people that you think might be able to help by using the @ but they must be people you have had some contact with. 

I now know @frustrated user (you) and this sentence notified you that something is happening in your thread.

I don't use 926, but what you describe is either (a) software glitch (call or chat with support) or (b) user input error (you need to do a careful review of all input). 

My guess (and only a guess, since I can't access your input) is that you did not indicate the entity is a trust in the General Client Information.

Intuit wants you to think this forum is support. In a sense, it is, but it is ONLY INPUT FROM OTHER USERS. We are volunteers and generally enjoy helping others. Sometimes we chide a bit and may rub you wrong, but we mean well and we like to have a bit of joy in our life. 

If you can give more detail about your problem, please do so and maybe we can help.
