You can go into your return and in the upper right corner is "forms" it pulls up your tax return and you can see the entries made. It's possible you transposed a number when you were keying in your wages. Capital Gains are Schedule D so just click on that "form" and you should be able to see what was input
OP is asking from TT Online, which does not have Forms mode.
Apparently, after e-filing (online version) doesn't have any other options other than print/download. There are no pointers as to how to get the forms.
@DawnC: Thanks for the hint. I could access the 1099-DIV sheets that I needed to verify, as suggested by the email from Turbotax. However, I couldn't see the information regarding direct debit payment from my bank. Would that be possible? I would like to reconfirm I have the right numbers for the transfer.
Included in your forms should be a cover sheet - I believe it is titled Filing Instructions and it may be multiple pages. It should show the payment method you used to pay your tax liabilities when you filed.. or can you clarify if you need some other info?
@DawnC: Thanks. That gave the information I wanted. I would have liked to be a little easier to access.
