Accidentally submitted Self assessment form before properly adding correct details

I started to look at my self assessment for 22/23 and accidentally submitted before fully completing . . is there a way of retrieving and resubmitting?

Hi naylorg,
If you submitted but not all the details are declared you can then go back and amend the tax return.
Our website Self Assessment tax returns If you need to change your return has more information about how to do this.
Thank you.
