In order to access a return prepared using TurboTax you need the account and user ID to look at the returns.
If you and your spouse are filing a joint tax return you have every right to know what is on that return. Your name is being signed to that return, making you legally obligated to any tax owed. Sounds like you have some big issues in your marriage if your spouse is concealing income information from you and you might want to seek some legal advice---which we do not provide here.
If past returns have been filed as joint returns, you should be able to get copies of them or get transcripts of them from the IRS and I highly recommend that you do so asap. Establish an online account with the IRS.
