Your 199A income is typically included in box 1 on your K-1 form and the Box 20Z income is included as part of this income. If you do not have income in K-1 Box 1, you will not get a deduction for 2020. However, it will carry over to the following year(s). When you sell your position, the adjustment will be made.
However, by not entering an amount at Box 20Z, but completing the entries later in the interview, from the supplemental information provided along with your K-1 form information, you will get Turbo Tax to complete without getting the "no income" error message, in order to complete and submit your tax returns (Federal and State).
Note: If you find amounts shown in more that one box 1, 2 or 3 on your K-1 form, Turbo Tax will require you to split the K-1 form into separate Turbo Tax K-1 forms, or you will get an error message. Turbo Tax asks this question earlier in the interview for the K-1 form entries. Make sure to click on this in order to split your K-1 forms into multiple K-1 for Turbo Tax to complete without producing an error message.
