TurboTax will automatically calculate the amount your son can transfer based on the income and other info you entered on your return. You’ll find the calculated amount on your Dependant Credit Summary.
For the eligible dependant claim, you son would have to have made less than your basic personal amount plus $2,350 since they were dependent on you because of a disability. For 2022 the basic personal amount is $14,398, so your son would have to have made less than $16,748.
