@garciabeck , from your post I am going to assume the following:
(a) the person in question is on J-2 and has workpermit
(b) the person has SSN associated with the workpermit
(c) 2021 is his first year on J-2 and is going to meet the substantial presence test i.e. he will be filing a form 1040
The fact that he has two different payors depositing payments in two countries is not material here -- what matters is that the work is being done in the USA and hence the income is US sourced and taxed by the USA. Suggest you tell us his home country also because a tax treaty between the USA and that "other" country may indeed impact taxability of income.
The reason for assuming that the person will meet Substantial Presence Test is because TurboTax ONLY supports form 1040 and NOT 1040-NR-- and not trying to determine whether the person is subject to world income or US sourced income only.
Does this answer your query ?
