<prompt> Human: I filled my tax return through HR Block. I had two jobs in 2017. There was a point where they asked me if I had another w-2 or had any other income, I dont have the w-2 from my other job, So I selected no thinking when I get that w-2 Ill just file that one separately. Well I had an irrelevant question so I called my mom, informed her of that since I was questioning myself, And she said that was a huge no no. HR Block just sent me a text saying my return has been excepted is being processed by the IRS. Was this a huge mess up, Or can it be fixed when I get my other w-2?  <response>: 1 for using the term tax return correctly.-1 for lying on the tax return.You can amend your tax return with a 1040X to include the missing information. Some people also said you can file a superseding tax return by paper before the due date. My suggestion is go back to HR Block when you have the W-2 and ask them what to do.Whatever you do, make sure you fix this by the April due date.
