Tax problems: bio parents claimed foster child as dependent

Ditto to everything above. I use a tax preparer so when the electronic filing bounced back, he asked me to get something to show when the girls arrived at my home. I asked the school where they enrolled to print out school records that showed date of enrollment. I also sent copies of the workers' reports that indicated date of placement. He then filed my return by mail. Interestingly, the state return went through electronically. It was the federal one that bounced back. I got the refund, then a really puzzling mailing from the IRS in October. Basically it said that I could have filed inappropriately (ie. claiming the girls), and if I did, here was my opportunity to fix things. When I called the info number they said I could basically ignore it. Good lucK!
