For client who itemizes on Sch. A, with charitable contributions > $4000, I cannot get rid of the Error Message on Line 10B on the 1040 Worksheet. I tried putting in $0, $0.10, $1, $250, and $300, and all give me an error message. I tried deleting it, still have an error. I clicked on "About charitable contributions", and the resulting help screen not only does NOT have this item, but many of the line numbers are wrong. What am I supposed to enter on 10b to clear this error message? Thank you all.
