Corrected W=2

[trberkovich]

I mailed my 2025 tax return and per certified mail, the IRS received it on February 26, 2026.  On March 3, 2026,  I received a corrected W-2.  I was advised to wait to receive my refund and then file an amended return.  Is this advice correct?  I am surprised that I have not received my refund yet (as of March 21, 2026).  Please advise.
