I lived in a foreign country for the entire year while my wife lived in Illinois. Based on Turbotax advice, I can file federal tax jointly and IL state tax separately. Turbotax tells me I don't need to file IL state tax. However, I have paid estimated tax for 2020 - how can I get the money back if I don't file IL state tax. In addition Turbotax showed much small amount refund than the estimated tax I have paid - even if I file the IL state tax. Anyone can help me to clarify what to do? I have small pension from the company in IL that I retired from, I also have some income from IL, however, most of my incomes are from dividends and interests, do I still have to the dividends and interests incomes to IL when I lived in a foreign country. I understand I may have to pay IL tax for the incomes from IL. Does Turbotax program have consider this situation? (I cannot take dividends/interests income out of my Federal income tax mock filing for IL State tax preparation, can I? Just for the purpose of calculating IL state tax I owe?) Please advise. Thanks.
