Legacy Self Assessment Tax Returns (from 2016-2019)

I'm trying to access my Self Assessment Tax Returns from 2016-17, 2017-18 & 2018-19, however, I can only find the summary overview information. Have the full returns been moved? How are they accessed? Thanks

Hi,
You can only view/print Self Assessment tax returns from the last 4 tax years.
At present the last tax year available is for 2020/21. If you require a copy of a tax return for an earlier tax year then you will need to contact HMRC to issue:
Self Assessment: general enquiries
Thank you.
