Can I make changes before "Submit your return"?

When I report the tax returns using the online self-assessment, is it true that I can make any changes before the step of "submit your return" ? (i.e. if I spot any incorrectness up to step "save your return", is it true that I can go back to previous steps to correct the fields?

Hi
Yes you can.

Hi HMRC Adm team, I submitted my tax return on 6 October 2024. As I would like to change my foreign tax relief, how to make the change after 72 hours? Ed
