Where’s My Refund / Where’s My Amended Return

The IRS issues most refunds in less than 21 days. 
Due to the delays of the pandemic, we have seen taxpayers getting refunds of delayed times up to 10 months.
Some returns may require additional time and the IRS explains it here: https://www.irs.gov/individuals/refund-timing
