Tax underpayment advice

Hello I have been told I made an underpayment of Tax in 22-23 and so my tax code has been adjusted for 24-25. In 22-23 I had 3 employers. My income was as follows: 1. Taxable Income: £20,991.19. Income tax paid: £2,168.60. NI paid: £1,644.62 2. Taxable Income: £24,192. Income tax paid: £4,838.40. NI paid: £1,568.05 3. Taxable Income: £18,264.48. Income tax paid: £3,652.80. NI paid: 1,446.76 My tax code from April 24 onwards says it will have a deduction for of £ 4,420 due an under payment. I want to confirm that this is correct.
