I filed taxes earlier in the year, owing around $60, which I paid with the filing. Then I got a Notice 54 with a check for $14, stating I would "be receiving a notice in a few days that explains why the check is different..."..."Please do not call us until you receive the notice."
It has been about 6 weeks now, and no "notice" has appeared. I know: this is small beans, but it is annoying. N.b.: No math errors noted on my straightforward (paper) return (copied from a spreadsheet I keep, which does the math, obviously).
Should I do anything but wait?
