How do i retrieve past tax return records prior to 7 or 8 yrs

Neither the IRS nor the TT program have records that old.

TurboTax and the IRS save tax returns for seven years.    You can get a transcript for returns as far back as ten years from the IRS---but not copies of the actual Form 1040's.

Or you can pay the IRS $43 for an actual copy of your tax return which will include copies of your W-2’s

If you want to keep copies of your tax returns for long periods of time then get into the habit of printing copies on paper for your own records.
