After you file

I finally checked USPS informed delivery yesterday and my IRS envelope was scanned! My mail date was March 4th so 3 days not bad. I ran to get my mail and received all but that refund! I freaked out and called the post office. They said sometimes, even though scanned, it may not come that day but the next. Atleast I know it's coming but this whole tax season is BS! Plus I'm in Illinois so that refund wont come until mid March. They stated none will be released until then. Illinois sucks too!
