Efiling itr 4s

I don't have a job/salary. l have 41000 as income in last FY from online advertisement. I am eligible to refund tax. In my efiling panel there is only itr 1 and itr4s I tried to submit 4s but following error occurred "For itr4s presumptive income is mandatory" I treated income as income from other sources. TDS is also treated as income from other sources. I want to refund the TDS paid hope you help
