Since you relocated outside the US during the year I think you are a dual status taxpayer required to file Form 1040NR. See the paragraph "Nonresident at the End of the Year" at https://www.irs.gov/individuals/international-taxpayers/taxation-of-dual-status-aliens
In general, people who are residents for US tax purposes are required to report to the US all income allocable to the period of residency. Based on the 1040NR instructions it appears to me that you will need to file a paper return.
Sorry I cannot be more helpful. Hopefully others may be. You have a complicated situation and I have not looked at the residency rules for the many years that I have been retired. But since you already know about the substantial presence rules perhaps you already have professional guidance?
