Unfortunately, you will not get your US taxes back.
Assuming you worked in the US in 2017, you can either file a dual status tax return (part year resident and part year nonresident) or you can file a full year resident US tax return with TurboTax and declare your worldwide income for calendar year 2018 and utilize foreign tax credit on your US tax return to help offset double taxation.
Dual status returns are complicated. With a dual status return, you are not allowed to use the standard deduction (only itemized deductions are allowed) and you are not allowed to use the married filing jointly resident filing status (you can only use single or married filing separately (if you are married).
In order to prepare
a dual status return in TurboTax, you will need to print a copy of the
nonresident return (Form 1040NR from the IRS website) for your tax on US income
after March. There will most likely be no US source income to enter for that
time. So your income on this form will probably be zero unless you
received US income after moving out of the US.. Write on the top of the 1st
page of the 1040NR, Dual Return. You will
need to write in your name and address and input zero as your US source income
(if that is the case). You also need to enter your filing status.

Then for the
resident part of the return you prepare in TurboTax, you are not allowed to use the standard deduction, only itemized
deductions if you are filing a dual status return. Also, you can either
file single (if you are single) or married filing separately.
You must suppress the standard deduction.
Instructions for this are below.
When your resident
part of the return is finished in TurboTax, print the return and write on top
of the return, Dual Statement.
Put the 1040NR on top of 1040 resident return and
staple and mail to the IRS. You must sign the 1040NR before
mailing. You do not need to sign the 1040 statement.
You will need to mail to the following address:
