It's not working for me either. I have tried inputting it on all of the 10 lines. I put the number in and it turns red with an error. Have a call in now. On this particular return, the taxpayer is a teacher and can take the $250 educator credit AND also had charitable contributions. It won't allow both the $250 and the $300.
Put the total amount on charitable contributions schedule A itemized deductions. The fact that $20 was from a W-2 that went directly to the sch A may be causing the problem.
Eg. If TP made total contribution of $125, enter that on schedule A.
Yes. It took 53 minutes with support to figure it out - they finally had me do that - put the difference between the charitable amount on the W-2 and $300 on the Schedule A as cash ($280) and then go back and do it on the 10b line. I told them that was a ridiculous amount of work, when it could be all built into that 10b line. but anyway...
Fair warning (from past experiences with the software) double check your work-around before you actually go to efile. By the time efile opens ProSeries programmers may have actually fixed the software and you don't want the software recomputing things using the correct data flow PLUS your work-around and either doubling things or cancelling things out (depending on what the work-around did).
My understanding is the same problem exists for contributions that flow through via K-1 so keep an eye on those too.
