Should I be mailing my federal taxes to UT and my state taxes to CT where i live

The mailing address for federal tax returns varies by your state of residence, and whether or not you are including a payment.  Please see the list below to locate your respective state and the appropriate mailing address for your federal tax return.

Form 1040 addresses for taxpayers living in the 50 states:

If you live in Connecticut...And you ARE NOT enclosing a payment use the First address; however, if you ARE enclosing a payment use the Second address:

Department of the Treasury
Internal Revenue Service
Ogden, UT 84201-0002

Internal Revenue Service
P.O. Box 37910
Hartford, CT 06176-7910

It took 8 days for my certified mail to the Ogden, UT address. Shouldn't it be only 2 business days to get there? From 1040 Instructions there is no mention of the Ogden, UT address. Is it right to send any 1040 returns to the Ogden address. Will I be in trouble filing 2014's returns to this address?
