@ajinkya_bankar , Since you entered US with F-1 visa in 2018 and assuming that this was your first /only entry within the prior three year period, you would have been on exempt status for five calendar years i.e. 12/31/22. Thus for the calendar you would have passed the SPT ( Substantial Presence Test) and be a resident for tax purposes. I suspect that you did not inform the broker that for 2023 you were an US person and they should have issued a 1099-DIV for the income. and taxes withheld.
Ideally you should ask the broker to correct this and issue you a 1099-DIV.
Else you can tell TurboTax that you have dividend income ( but no 1099-DIV) and essentially fill out the income as if you had received a 1099-DIV.
Please also consider downloading the 1042-S form ( it is 7 page doc --pdf ) and 1099-DIV form from www.ikrs.gov, search for 1042-S and 1099-DIV and familiarize yourself with the codes and notes on these forms. They both have income and federal tax withheld boxes.
Is there more I can do for you ?
