If you did not qualify for the foreign income tax exclusion, you should be able to take a foreign tax credit to help offset double taxation. Enter the phrase, foreign tax credit in the search box at the top of your screen and click on Jump to.
As long as your foreign income is included in with your wages on the1040, that is the important part. If you did not pay any foreign taxes in 2018 but will be taxed by China in 2019 for 2018 income, then for the foreign tax credit, just use the accrued method. Please let me know if you have questions.
