Deductions & credits

Possibly, but it depends on your status.  If you are a US Citizen and living abroad, then yes.  

If you are a nonresident alien or dual-status alien the probably not unless you meet an exception to the rule. If you are a nonresident alien, you would need to file using Sprintax instead of TurboTax as TurboTax does not handle form 1040NR

"Certain taxpayers aren't entitled to the standard deduction:

1. A married individual filing as married filing separately whose spouse itemizes deductions
2. An individual who was a nonresident alien or dual status alien during the year (see below for certain exceptions)
3. An individual who files a return for a period of less than 12 months due to a change in his or her annual accounting period
4. An estate or trust, common trust fund, or partnership

However, certain individuals who were nonresident aliens or dual status aliens during the year may take the standard deduction in the following cases:

• A nonresident alien who is married to a U.S. citizen or resident alien at the end of the tax year and makes a joint election with his or her spouse to be treated as a U.S. resident for the entire tax year;
• A nonresident alien at the beginning of the tax year who is a U.S. citizen or resident by the end of the tax year, is married to a U.S. citizen or resident at the end of such tax year, and makes a joint election with his or her spouse to be treated as a U.S. resident for the entire tax year; and
• Students and business apprentices who are residents of India and are eligible for benefits under paragraph 2 of Article 21 (Payments Received by Students and Apprentices) of the United States-India Income Tax Treaty" https://www.irs.gov/taxtopics/tc551
