Q) I need transcripts from irs confirming my recent filing of my back tax years. 2008, 2012, 13, 14, & 15. How do i get these?

A) According to the IRS: You can get a transcript by mail to view your tax account transactions or line-by-line tax return information for a specific tax year. The method you used to file your return and whether you have a refund or balance due, affects your current year transcript availability. Note: If you need a copy of your return, you must use Form 4506, Request for Copy of Return. https://www.irs.gov/Individuals/Get-Transcript
