Itr to fill if capital gains are negative or very minimual (rs 100-200)

Hello,

I have a query regarding which type of ITR to file for a specific case. My wife did some trading last financial year for learning purposes, and ended up with quite a few small transactions of 1-2 shares each. Resulting capital gain is around Rs 200, and even that becomes negatives after adjusting for taxes and expenses such as brokerage, etc. She is a housewife and doesn't have any other income except for interest on savings and FDs, which also is lesser than taxable limit. We still want to file ITR to claim refund on TDS deducted by banks. Which ITR should we file - ITR 1 or ITR 2?

Thanks in advance.
