When you were on F-1 visa, you were considered as an exempt individual, not counting days being present in US for five years 2013-2017. As you changed to H-1 visa, IRS started counting your days from October 1, 2015 and since you did not meet the Substantial Presence Test , ( only 90 days ) you are considered as a nonresident filing form 1040-NR for 2015. You will need to use Sprintax to complete your 2015 filing as TurboTax does not support the nonresident form.
However,
If you anticipated you would be staying in US for at least 183 days in 2016, you can make an election FirstYearChoice to claim yourself as a resident from October 1, 2015. This way, you will be considered as a dual-status alien. You will be filing as a nonresident 1040-NR from January 1st to September 30, 2015 ( Report only US source income ) and a resident filing form 1040 from October 1st- December 31, 2015. ( Report worldwide income).
You cannot file Form 1040 or the statement until you meet the
substantial presence test in 2016. If you have not met the
test by April 15 2016, you can
request an extension of time for filing your Form 1040 until a
reasonable period after you have met that test. To request an extension
to file until October 15 of the following year, use Form 4868,
Application for Automatic Extension of Time to File U.S. Individual
Income Tax Return. Once you make the first-year choice, you may not revoke it without the approval of the Internal Revenue Service.
If you are filing dual-status, you can still
use TurboTax program to prepare your portion for being a resident ( October-December),
however you will not e file your form 1040. Instead, you will print and
attach it to your form 1040NR and mail them together with any required
documentation to the IRS location at Austin TX.
