@AZAZA , it would be helpful if you could answer the same questions that were posed above.
In general , however, and assuming that (a) you are a resident for tax purposes; (b) there is no treaty impacts/ assertions and (c) you are living in the USA, I would enter the interest income from 1042 as if you had received a 1099-INT or DIV whichever is applicable and enter any taxes withheld in the appropriate area on 1040.
Is there more I can do for you ?
