Test

Hello! Originally I wanted to transfer my wife's wedding allowance to me. But I made a mistake in applying for wedding allowance transfer to her online on my gateway. Question one I am a taxpayer and my wife is a non-taxpayer. Two months ago, I made a mistake in applying to transfer my marriage allowance to my wife. Can I cancel the wedding allowance directly to my wife on my gateway online? Question 2 At the same time in the tax year 22-23, I also mistakenly transferred my wedding allowance to my wife. As a result, my tax exemption amount is reduced (I suddenly have to lose the tax exemption amount of £13,820 - £11,310 = £2,510). Can I get back the tax I overpaid? Thanks!
