@IccamoconYEARS ago, I had a huge fight because my numbers didn't match up. I electronically filed my federal and manually filed my state. Manually filing I used cents i.e. 49.54 vs $50. When everything was over and done there was about $3 in rounding errors. It took forever to correct the problem.
As I stated previously, I have received another form because I filed too soon (I thought I'd already gotten their form but I had two coming). If you have another form lost in the mail and the IRS received it electronically, they could be correcting or rejecting your return based on new electronic information.
Unfortunately, I wouldn't count on your refund money anything soon if you haven't gotten it already - it's a really big line. The good news is that these electronic differences are usually quickly rectified by a letter in the mail telling you about the descrepancy.
