I have a question our federal tax was sent a check & it got mail out July 10th & it said mailed now it says pending then next it says return delivery what does that mean

@mamabear798588719 where does it state "return delivery"  (what website, a letter, etc.) and can you post EXACTLY what the sentence states?  

Also, if you enlcosed a check with the tax return, the check should have cleared you banking account very quickly.  Did it? if not, it could be an issue with how you filled out the check.

Please clarify what got mailed out on July 10. Is that when you mailed your federal tax return to the IRS, with a check enclosed with the tax return to pay the tax that you owed? Or did the IRS say that they mailed your refund check to you on July 10?

What is "it" that said "mailed" and now says "return delivery"? Is that exactly what "it" says?

If you mailed your tax return with a check to pay your tax, did you mail it to the correct address for a tax return with payment enclosed?
