Confused about form P55, claiming tax back from pension

Iwanttobefree

Have taken out a lump sum from my drawdown pension to pay the remainder of my mortgage (all discussed months ago) , I paid most off in December, but left some until now to get the extra tax allowance as I cant work due to health issues,  (contribution based ESA support group) and will only get £5914.60 of taxable benefits during the tax year

Aviva have sent me an email saying to phone up HMRC and quote their employment ref along with my NI number to claim back.  I did this using the online form P55  in December but suffer memory issues (not dementia) and can't remember how I did it.

I have two choices, fill out the section

Do you expect to receive income from any UK pension during the current tax year?

which I feel is the wrong section as it implies I'm getting a regular income, however that section does allow me to put in Avivas employment ref number

or

Have you received any pension flexibility payments?

which I would have thought is what I have done as it's another lump sum taken from a drawdown pension, but this section simply asks for the Pension providers name, the amount I took out and the amount of tax they took off, it does not allow me to put in their employment ref code.

Should I just fill out the flexability section?  If I click on the PAYE section of my HMRC account, it shows the payment Aviva made to me today.

I did try phoning HMRC  (which understandably is a bad idea at this present time) , after listening to 10 mins of virus/self employed... advice, after taking my details and security checking me, I got put through to wait for an adviser, then got a message they are too busy, phone back later and was cut off.

Many thanks
