Where to claim job expenses on self-assessment?

losh11

I'm a software developer, who works from home and purchases all my equipment, including my computers. According to Buying other Equiment, for tax relief for employees page on the HMRC website, I qualify under all the conditions to claim tax relief. The website also mentions if claiming more than £2,500, it must be done through a self-assessment, so I've requested self-assessment from April '19 - April '23.

However this is where I've hit a roadblock. I'm not sure under which section I can do this on the online self-assessment.

As I've also been working from home - as my employer has no physical office - I will also be applying for 'working from home' tax relief. From what I understand this is filled in on the (4) Fill in your Return section > Change expenses which have not been reimbursed > Other expense and capital allowances.

IF the expenses are allowable, everything that you have mentioned goes in the ‘other expenses and capital allowances’ box. 

IF the computer is an allowable expense you would be claiming capital allowances (AIA)

It's pretty unusual for a salaried employee to need to swallow the cost of a PC that's wholly and exclusively to do their job; is the plural "my computers" intentional (as in, you need to buy and own more than one)?
