I already filed 2023 FBAR for my foreign saving and securities account. When I filed my tax return online, I realized I had $2800 gain in my foreign securities account in 2023, I think I also need to report it on schedule D although I did not have 1099B. However, I still need to report as a bulk sales for those gains to determine whether the stock sales are short term or long term. I also checked yes on FATCA filing requirement because I believe I need to report the gain on FORM 8938 as well. My question here is can I just put all $2800 gain to short term to be secured because I can't check back the details on my foreign account and short term gain usually with higher tax. Since I only have some interest income and dividend income to report and I don't have income in US, my tax is 0 anyways as my AGI do not exceed the standard deduction limit. Please advise, thank you so much.
