ITR for salary and non-salary

Are you asking for the ITR form to be filled?

Yes, I want to know which ITR form will be applicable.

Are you a freelancer??

1) I am confused for the fact that why they have deducted TDS u/s 194J for salary. The correct section for deduction is 192.

It seems from your post that you are a regular employee and not freelancer, if this is the case then you can go for itr-1.
However, for freelancers itr-4 is prescribed if you maintain books of accounts, if not and your income is not more than Rs.50Lac then you can itr-4s if you opt so. Under this your income will be deemed to be 50% of gross receipts.

I have income total 3,00,00/- .
Company deduct TDS @ 10% for under probation period.

Please suggest me which ITR to be used.

Please reply.
