Permitted work time sheet query

Hi. I'm looking for some of your wonderful advice again please?

I've been in the Support Group for about 5 years & sent back my latest ESA50 last week.
I had sent the PW1 form to DWP in January with an accompanying letter explaining why & how I was going to work (self employed selling online / recommendation of my consultant to break monotony of coping with long term illness etc).

I finally received a response to the PW1 today, asking me for evidence of my earnings, expenses etc, which makes sense, as they need to check my earnings arent over the threshold. But they have also sent a weekly time sheet for me to fill in from Jan to now & I'm a bit confused how to fill this in. I realise they need this to make sure I dont work over the hours (I wish I were able to get even close to the limit )

I have the full support of my 2 carers (they take it in turns) to help me with the business, and they take over for me when I cant manage if something needs sorting urgently eg. they answer queries or pack & post by themselves. I explained in the PW1 & the latest ESA50 that I can't manage any of it without their input, eg. if I list something online one of them needs to check the listing before it goes live to make sure it makes sense, get rid of errors etc.

So do I fill in the time I spend totally on my own on the business (as this is always checked/reviewed, does it even really count as on my own?) Or do i put in the time I put in with 1-1 support? Do I mention the additional time my carers spend working without me - there is no way I could make it viable without them doing the additional time?

Thank you as always
