Deductions & credits

I am guessing you have already filed your taxes by now.  If it helps anyone, here is what I did:

 - E-filed through TT (on 4/14/22) and it printed the form 3115 along with 8453 (form to show you have e-filed your 1040)

 - Then I mailed (on 4/18/22) the two forms, along with an attachment showing the depreciation calculations & other info, to the IRS address printed on 8453 (You may fax it)

 - Then I mailed a signed copy of 3115 to the Ogden UT address
