UPDATED FOR TAX YEAR 2019
You may use your own address for data entry on Schedule K-1, if the partnership has a foreign address.
The most important items on the K-1 are the EIN and name of the business. The K-1 general information is not filed with your tax return; and the values from the K-1 flow to Schedule E and other respective forms.
It is not a problem to enter a different address.
