If you are asking how to file an extension for 2021, it is too late. Now your 2021 return is just late. If you are getting a refund then there is no penalty for filing past the deadline. If you owe tax due, your interest and penalties began on April 18, 2022. File asap and pay your tax due. The IRS will bill you later for any additional amount owed---it will not be calculated by the tax software.
