I went to "1099-misc/nec" section and entered the amount of IT-2568 in the box "state withholding" box.

Then the Critical Diagnostics increased, asking to enter "income" and EIN of the payer.

Since IT-2568 estimated tax was paid by the partnership regardless each partner's income or compensation, there is no way for this withholding to be a tax against the partner compensation,which was none.  The partnership did not pay any compensation to partners.

Did I do wrong, when I went to "1099-misc" section, from "SS benefits, Alimony, misc income" section?

Would you please explain more in detail about where to go to enter the amount of IT-2568 tax paid by the partnership?
