Thank you for your help. 

it's $105 withholding not any big amount. maybe I will enter it to Line 25B.

 But people will encounter this situation in which they file form 1040 (not form 1040NR) at the same time, they receive a form 1042-S from their job or other sources. If you search this question online, there is a solution for Turbotax to resolve or how to enter it.  But not proconnect online.

Hope someone knows a better way to handle this in Proconnect.
