Retirement tax questions

Hello @LindaS5247, and @AmyC :  I was reading the post from last year, I also have NR4 withe income code 39.  I treat the NR4 as if it is a SSA-1099 and entered it in the Retirement Plans and Social Security section, under ‘Social Security (SSA-1099, RRB-1099)’, however,  I am having issues on the "Deduction" of the Foreign Taxes part,  under the deductions&credits, Foreign Taxes I selected "tax credit",  which takes me to questions for form 1116, and I am not sure what to choose for "Income Category Type".  Is that the correct way? if so, what is the "Income Category Type"? Any help is greatly appreciated.
