I filed my ITR for AY 2018-19 with claiming tax relief u/s 89 for the arrears of salary of last financial year . For that, I filled form 10e also before submiting my ITR. But now, I have received Intimation U/S 143(1) in which they rejected my claim. Now, when I am going for rectification, the AY 2018-19 is not showing up. Please guide what to do?
