I started my IRA Account contributing the maximum allowed for that year and took tax exemption for it. I did not take any tax exemption for all other subsequent contributions. I have now withdrawn the entire fund from the investment company. How should I enter the amount withdrawn on my Tax returns.
If the withdrawal occurred in 2018 then you should have received a Form 1099-R from the investment company for the withdrawal. The 1099-R is entered on your tax return as received on your 2018 tax return.
If the withdrawal occurred in 2019 then the investment company will send you a Form 1099-R in January of 2020 so you can report the withdrawal on your 2019 tax return.
