Form 16 A For Zero Tax For Salaried Employee

NSDL site only allows Form 16 part A for employees whose Income Tax in deducted.
I have worked with two companies in the same FY. Tax is 0 in each company but when I combine the income I have some Income Tax to be paid. I could not file my IT return as Form 16 A is not available from either company.
How do I file my return without Form 16

Dear Friend,
While Filling Income Tax Returns associate need to consolidate his/her total Income if having two Forms -16’s in the same financial year. As you mentioned above we can only download the Form 16’s whose tax has been deducted during the Financial Year, as employer will furnish Annexure -2 of Tax deductees.
However, employee can request employer for NIL Form No: 16, upon request they will issue the same.
Hence, you can request for the same to your ex and current employer for obtaitaing Form -16.
Thanks,
