I entered the income from a K-1 on the "Enter Box 1 Info" form for 2019. However, this income and other data does not show up in the Summary of K-1s ( I have 4 of them to report). I don't understand.
The K-1 summary screen typically shows "$0" because the entries from your K-1(s) are distributed to the appropriate schedules and forms on your return.
For example, interest and dividends would appear on Schedule B while capital gains would generally appear on Schedule D.
