If you believe your refund is not correct, you can always request a copy of your refund/statement directly from the IRS. The link to that website is provided below:

If that does not help, you can check your previous year's Tax Timeline in "TurboTax" to see if the refund amounts are similar. If you have already e-filed your return and it went through successfully, you will not be able to amend the return online. HOWEVER, you can still amend the return via paper mail even if it successfully went through electronically. This
option will allow you to enter any information you may have been missing on your e-filing refund. 

I hope this answer helps and guides you in a positive direction. 

Best of luck!
