Irrespective of when you get paid, what is to be considered ( and restricted ) is when the work is done. Thus if the work was completed before the adjustment of visa status, then the earning applies to that F-1 status. The H-1B work visa is limited to and for the benefit of the sponsoring entity -- you cannot leave that employer and be compliant with the conditions of the visa. I am assuming from your non-response as to when you entered the country with F-1 and that you were on an extension for OPT, that you must have already outlived your five calendar year exemption for counting days present towards substantial presence --- so you probably are going to be a Resident Alien for tax purposes during 2019 and therefore file a form 1040. Note that TurboTax does not provide support for 1040-NR ( they generally refer these to their partner SprinTax for such filing ).
Does this answer your question or you need more help ?
