Part time freelancing income - ITR filing doubts

Hi, I have a proper full time job. I freelanced for a month last year. They got my PAN and whenever they paid me in my bank account, total amount is ~1.4L, they deducted TDS under 194C (it's 1% TDS). This freelancing income is listed in my AIS as Business receipts - Receipts from contract (Section 194C). The amount was paid from an entity 'XYZ private limited' even though I worked for an individual..My questions are

1. Which ITR form to use?
2. I tried filling ITR1 form. It's not showing my freelancing income in 'Gross Total Income' section. But the TDS deducted by them is shown under 'Taxes Paid' section. I am confused whether I have to add this 1.4L rupees in as Other sources of income in 'Gross Total Income' section or not. Should I? I am confused because it's showing in AIS but not in ITR form. Could you please help?
