@Cambrionario , what do you mean by first year as a resident followed by suggestion that this is first US return? Please tell-- (a) what visa are you on; (b) when did you enter the USA; (c) did you have any days present in the USA during 2016, 2017 in addition to 2018 ( for any cause and under any visa ); (d) which country are you from. First you have to determine if you are a US resident ( GreenCard )/ resident for tax purposes / Non-Resident Alien, because while form 1040 is supported by TurboTax, the form 1040-NR ( for non-resident filing ) is not. You could also be dual status tax payer. Please answer the questions above.
Absolutely agree with @rjs , to the extent that you are a form 1040 filer.
