Yes, I meet the critrieria for 2018 but still I do have problems with 2017. I have filed my tax but IRS had sent me letter to verify my Identity for the tax return but unfortunately I did not get the letter. I contacted IRS yesterday about my issue, they (IRS) told me that they are sending the letter again. Now I am pretty sure that I made mistake while filing the tax return for 2017, so for that IRS had sent me letter. What I have to do now?
