SE return expected?

I am a pensioner with state pension and a small property investment return. As my income is below allowance level I was sent a "Withdrawing notice to File"letter in 2019, and was told that this would carry over unless my circumstances changed. I went online 2 months ago to check my situation and was issued a new reference number. I completed the questionnaire as to whether SE return required, which indicated that no submission was required. Since then I am getting emails from HMRC regarding help with filling out SE, is this indicative that a return is expected? My personal tax page indicates nothing about a return being due.... can I assume that I do not need to submit unless circumstances change?

Hi,

As the Self Assessment tool advises a tax return is not required and you are receiving texts encouraging you to complete a Self Assessment tax return, we would suggest to contact our Self Assessment team.

Self Assessment: general enquiries  

We can then check your Self Assessment account is dormant.

If you have more than one 10 digit UTR number, we would also suggest to also raise this issue.

Thank you.
