I made the same mistake and I also got my tax refund and recently got the stimulus check deposit.
I want to file an amendment and file form 1040NR through Sprintax.
However, when I click on the option that says I already filed 2019 taxes and need an amendment, Sprintax pauses the whole process and tells me that this needs to be treated offline.
I tried this 2 weeks ago and still waiting to be contacted by someone offline.
Can you please advice:
1) How long do I need to wait to be able to generate 1040NR form with Sprintax to include it in my amendment.
2) I got an stimlulus check because I made the mistake of filing as a resident. How do I give back this money to IRS?
Thank you!
