Awaiting for approval of IRS,,,after the approval of the 2017 tax where would I find my 2017 return??

2017 tax returns are not due until 2018. I think you mean where do you find your 2016 return after the IRS approves them. The best way to find your return is to login to your Turbo Tax account and click my tax timeline and they will show there. If you want to check your 2016 refund you can check the federal here: https://www.irs.gov/refunds
