My first self assessment.....Help!

Just completed my first self assessment tax return but not yet hit the 'submit' button (all because I'm now in receipt of a tiny Netherlands state pension). I think I've done ok , however when I viewed my calculation the 10% Married personal allowance from my wife's account was missing, leaving me only with the £12,570 standard personal allowance. Before self assessment I'd benefitted from the £1,260 extra allowance for the last few years. Am I dong something wrong?

Hi Pancho99! alderton,
Ensure that your marital status is specified on the dropdown near the start of the return.
If the transfer still is not present in your calculation, and you both still meet the criteria for Marriage Allowance
Marriage Allowance
Please request your wife  to contact us to restablish the transfer if necessary. 
Thank you.
