making out

I'm a little stuck... Click here to teach me more about this clue!

'writing the cheque' is the definition.
'making out' can be an answer for 'writing' (making out is a kind of writing). I am unsure of the 'the cheque' bit.

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for making out that I've seen before include "Pretending" , "managing to get on" .)

I've seen this clue in the Evening Standard.
