Hi everyone, I worked in the US in 2014 and 2015 and did my tax return with Turbotax, it was more than 1000$, but I never received check or bank transfer. What can I do ?

Well hate to be the bearer of bad news but it is too late to get those refunds reissued ... you should have ask about 3 years ago.  

Thanks for this super quick reply ! I did fill up all the documents and confirmed everything back then. I just never received the check... :(

Also I asked the payment to be reissued back in 2017 they said they would send another check... still didn't receive a thing !
