However I hear a tax professional CPA can file the past two years electronically, so does that mean the returns will be machine scanned and will only take about two weeks to process?
Some paid tax professionals (avoid high priced CPAs) can efile prior year returns ... when the IRS opens efiling in January 2022 the 2019, 2020 & 2021 returns can be efiled but don't count on a 3 week processing time as a certainty. The IRS has been taking much longer to process all returns lately and mailed in returns have been taking 4 to 6 months or longer.
