It's been way past the time I should have had a refund.  If they say there's no record of it being received by mail, can I electronically file another one?

No, you would not file another return. That could cause issues and delays for both. The IRS asks you wait 4 weeks after you mail your return before looking up your refund at Where's My Refund? If you did not use certified mail to send your tax return, you can try checking your tax return with the IRS by ordering a tax transcript from the IRS, to see if it was received. This is a free service and is usually processed the same day. Please click this link to order a tax transcript: Welcome to Get Transcript

Also, be sure when checking Where’s My Federal Refund? site that you are entering only your Federal refund amount. This can be found on your Federal form 1040, line 21a. If you paid any fees out of your federal refund, use the refund figure prior to the deduction of he fees. Also if you filed joint, be sure to enter the filers name that appears first on the return.
