Employment Expenses for Self Assessment

[happybee]

I am in the process of completing my self assessment for 2017/2018. I had 3 employments during that financial year.
The first employment (with NHS)was for my pay for the month of April 2017 when I retired. My second employment is for when I joined the agency(private contractor - with different uniforms) and worked with them for about 4 months (April to July). My third employment (with NHS) was for when I returned to my 'old job' on a part-time basis from August 2017.

I know I can claim for my annual professional indemnity and journal subscriptions. Can I claim 3 expenses for the three employments or for only 2 expenses as I returned to my 'old job' in August 2017?

Thanks in advance.

You can't claim more than you paid if that's what you're asking.
