Which address should I mail my Federal tax (I live in CA now)?

[luzhan11]

I currently live in California and I mailed my Federal Priority Overnight tax via Fedex today (May 16) to the address listed in IRS website
https://www.irs.gov/filing/submission-processing-center-street-addresses-for-private-delivery-servic...
:
Fresno - Internal Revenue Submission Processing Center
5045 East Butler Avenue,
Fresno, CA 93727

but this address is different from the instructions from Turbotax:
Department of the Treasury
Internal Revenue Service
Fresno, CA xxxxx-xxxx

Fedex will deliver on May 18. But since the IRS address is different from Turbotax address, I am concerned if Fedex will deliver successfully. And I will not know about this till May 18, which is past the May 17 deadline.

So, I have 2 questions:
1. which address should I mail the Federal tax return to in CA?
2. what can I do if the Fedex cannot deliver successfully on Tu (shipping date is May 17

The address listed in TurboTax is the IRS mailing address for tax returns sent through the U.S. mail.

Tax returns sent by private carrier such as FedEx or UPS use the other address since private carriers need a physical address to delivery packages.

Your return should count as being timely filed if it bears a private postmark on or before the filing date.
