You will need to file a US federal tax return. You will pay capital gains on income earned world wide, including Puerto Rico. You will also need to file a partial year or non-resident tax return with Oregon. TurboTax will help you every step of the way.
TurboTax does not support filing a tax return for the territory of Puerto Rico. You will have to file this directly with the Department of Treasury of Puerto Rico. There is no capital gains tax in PR, but you must be a resident for the entire year.
