I came to US in Feb 2017. I received bonus for 17 in 2018. Bonus for (jan-feb) was taxed in India, (mar-dec) was tax in US. Do I've to add (jan-feb) bonus in 2018 income?

The  (jan-feb 2017) part of bonus was also transferred to me in 2018 in US bank account by my employer. But my employer has deducted india income tax on that. Do I have to include (jan-feb 2017)  bonus income as US income. The (jan-feb 2017)  bonus is not including in my W2.
