File revised itr after partial tax refund

Hello,

I have filed FY 2017-18 income tax incorrectly with 440/- INR tax refund which got credited to my account recently. I took a look at my Form 26AS yesterday and found that the actual tax refund should be 3120/- INR. I believe I can file revised ITR now but I don't know where to mention 440/- INR in it. There is no place to write this amount anywhere online or may be I couldn't see it. Is it my responsibility to tell this to Income tax department or will Assessing officer have this information handy?

Can someone please help?

Regards,
Ankit
