I have the following things which are in the list of documents to be uploaded -- need your help any information is really appreciated
1. A letter from relative(s) or friend(s) confirming I or my partner lived with them for some or all of the 2-year period --------------- not sure what this one means? do they need a letter from relative(s) or friend(s) that we (myself & my wife) lived with them for some time (months or years) -- I am not living in the same address for last the 2 years -- I am missing it by a month or 2 --- (1 year & 10 to 11 months) --- if you have any format for the letter that would be really great


2. Evidence of monthly housing costs for the accommodation in the UK where you live or will live ------------- do they mean that we have to upload the utility bills ... like Gas, Electricity, Water, Council tax & telephone bills?----- that are ready they have listed separately then why they are asking this separately
----------------------Document type----------------
3. Residence in the UK --- do they mean BRP? if yes -- already they have asked to upload the BRP as a mandatory documents
4. Proof of business ---- I do not have any business, then why this question --- what should I do here?

Optional documents
Below is a list of optional document categories. Please ensure you read the supporting document guidance on GOV.UK for your application route before including documents in the below categories. --------- not able to find the what document we need to upload in under which category from GOV.UK
The application is very confusing
