Client who has had sub-poverty level wages for a long time, had 50K of income due to a K1 fro a poorly handled (IMHO) estate. IRS wants to be sure she really filed the return and they want copies of all W2s, 1099s, etc. This became a refund return because I had her pay in enough on 4/15 with extension, so I understand the IRS computer questioning this, but the refund was only $90 so they shouldn't be wasting everyone's time.
