I'm green card holder since 2015 and my wife was F1 student since 2018. I selected to treat my wife as resident alien for joint filing last year (tax year 2018) and used TurboTax as e-filing, everything was fine (we got the refund). Now I realized that I should attach a statement for making Non-Resident Spouse as Resident Alien for the first time joint filing, and do paper-mailing way for 2018 tax reporting.
Can I attach the statement and do paper-mailing way (I need to use US-China treaty and do paper-mailing anyway this year) for 2019 tax reporting? As there is no amount changes, do I still need to use 1040X about this, or just attach the statement? In the statement, should I declare my wife was treated as resident alien sine 2018 tax reporting (like a amend against 2018) or 2019?
Or I can still do normal joint filing as paper-mailing way for 2019 tax reporting. Later on, send the statement and explanation (with 1040X? no amount changes at all) to IRS, separately. Please suggest. Thanks.
Please help. Thank.
