Quicko prepares & uploads your ITR on IT Department (ITD) when you click on E-File. Once uploaded your ITR can end up in either of following states
1) Processed: In this case, ITD processes and acknowledges your ITR by generating a unique Acknowledgement commonly known as ITR-V. You will receive the same in an email to your registered email address (Where can I find my ITR-V acknowledgment?)
Note: As due date draws closer, lacs of tax-filers are uploading their ITRs to ITD, slowing downs ITD processing. Hence you may see delay of up to 24 hours in receiving your acknowledgement.
2) Failed: Your ITR may fail for multiple reasons. You can read more about reasons for failures and how to fix them here.
