@ajinkya_bankar , assuming that there are no qualified dividends on 1042-S, my mapping of this to 1099-div is as follows:
1099-DIV -------------------------- From 1042-S
Payer's Name >>>>>>>>>>>>>>Box 16(a)
Payer's TIN >>>>>>>>>>>>>>> Box 16(b)
Box 1(a) total ord. divs. >>>>>>>>Box 2
Box 4 -Fedl. Tax withheld >>>>>>> Box 7(a)
Hope this helps in mapping one to the other . Let me know if you need more on this
