@SusanY1 Whoa I’m so confused. I thought IRS says it’s
“Internal Revenue Service
P.O. Box 409101
Ogden, UT 84409”
(https://www.irs.gov/filing/where-to-[product key removed]ning-with-the-number-3)
do you thinks it’s possible that the address you mentioned is only for returns, extensions and payments? (https://www.irs.gov/filing/submission-processing-center-street-addresses-for-private-delivery-servic...) And I guess 3520 is neither of them?
