I already have a tax code which shows I have marriage tax allowance being transferred to me from my spouse. How do I include this on the self assessment tax return? I can see the button if I wanted to transfer my tax allowance to my spouse, but I can't see how to say I've had it transferred to me. I feel like this belongs in one of the final under/over payment boxes (relating to my tax code) but I don't know which and it doesn't feel right when reading the descriptions.
