Thanks, Ernie. Really appreciate your reply. I was resident in 2019 too on an L visa, so I'm fairly sure the dual status is the way forward.
Just to be clear - TT is still recommending I take the standard deduction, which I believe I cannot do, right? Should I just override this with itemised, or do I need to tell the software somewhere this is a dual return (as I guess it hasn't recognised this). Thanks.
