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

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
