It sounds like you may indeed be deemed a resident alien for 2019. Please see the irs website and verify that yourself (or ask your tax advisor).

Is so then you file a 1040 just like any other resident or US citizen. As to how to enter that info into turbotax see:

Also note that it is possible that the tax treaty between the US and your country may come into play. If there is one. If your current county taxes you on the same income they might give a credit for US tax paid or the tax treaty might dictate a different treatment (perhaps the US would give you the Foreign Tax Credit.) That is a super complicated area of taxes.
