Can you file 1098-E forms from previous years if you never filed them

No, you cannot put 1098E's from past years on your 2023 tax return.  If you want to enter them, you can amend those past year returns.    But you cannot get any additional refund for a tax year earlier than 2020.   It is too late to amend 2018 or 2019 and get a bigger refund.
