The I.R.S. has rejected my efiling stating that another taxpayer claimed my daughters ssn# as a dependent. She did this by mistake and her return has been processed and a check mailed. She used a online source to efile her return. Can she file a amended return thru any other efile source, such as turbo tax ? Do we have to wait until her check comes and return it by mail b4 filing a amended return. She was overpaid because of her claiming herself on the 1st filing. Of course our state taxes are in the same purgatory!...Please Help...and thanks....
