Thanks DawnC!
My question is how to calcualte the cost basis because the tax first time paid is in foreign countries when stocks were vested before I moved in US, thus neither W2 in 2018 nor 2019 has included the capital gain when they were vested in 2018. So it looks like I could not enter any cost basis at least for RSU for the tax filing in 2019, and thus the cost basis for RSU would be zero and will induce lots of double tax. Althought the cost basis is already shown in my ETRADE account for these stocks.
In another hand, the excessive credit from 2018 could not be used in 2019 and most likely later years due to no foreign income. So I have to pay for the double tax and no other good options. Really depressed!
