If you received a distribution in 2019 from a traditional IRA and you also made contributions to a traditional IRA for 2019 that may not be fully deductible because of the income limits, you can use Worksheet 1-1 to figure how much of your 2019 IRA distribution is tax free and how much is taxable. Then you can figure the amount of nondeductible contributions to report on Form 8606. Follow the instructions under Reporting your nontaxable distribution on Form 8606, next, to figure your remaining basis after the distribution.
