Hello @rhibrai-ig-gmail,
Let me help share how you can set up your self-employed profile so you can determine when should you need to file your tax return.
Normally, QuickBooks will let you set up your tax profile for tax return calculation covering the period from April of the current year to April of the following year.
In the same manner, here's an article you can read to learn more about your tax profile: QuickBooks Self-Employed UK Tax Profile Set Up.
However, I'd still recommend contacting the HMRC so one of their specialists can help you and confirm your tax return filing.
On top of that, I've got you this helpful article for guidance in preparation for the 2020 tax season: QuickBooks Self-Employed Annual Tax Guide.
If there's anything else that I can help you with, please let me know by leaving any comments below. I'll be here to lend a hand.
