@long210845 Why have you been filing separate returns? That is usually the worst way to file.
If you were legally married at the end of 2020 your filing choices are married filing jointly or married filing separately.
Married Filing Jointly is usually better, even if one spouse had little or no income. When you file a joint return, you and your spouse will get the married filing jointly standard deduction of $24,800 (+$1300 for each spouse 65 or older) You are eligible for more credits including education credits, earned income credit, child and dependent care credit, and a larger income limit to receive the child tax credit.
If you choose to file married filing separately, both spouses have to file the same way—either you both itemize or you both use standard deduction. Your tax rate will be higher than on a joint return. Some of the special rules for filing separately include: you cannot get earned income credit, education credits, adoption credits, or deductions for student loan interest. A higher percent of your Social Security benefits may be taxable. Your limit for SALT (state and local taxes and sales tax) will be only $5000 per spouse. In many cases you will not be able to take the child and dependent care credit. The amount you can contribute to a retirement account will be affected. If you live in a community property state, you will be required to provide additional information regarding your spouse’s income. ( Community property states: AZ, CA, ID, LA, NV, NM, TX, WA, WI)
If you are using online TurboTax to prepare your returns, you will need to prepare two separate returns and pay twice.

As for your tax files being on a TurboTax account----paid tax preparers are not allowed to use TurboTax to prepare returns for clients. A paid tax preparer would have to use the professional tax software --- and there is no way for you to gain access to those files. Do you have copies of the returns---or did the tax preparer put the files on a flash drive or some other back up device for your use?
Or by "tax preparer" are you referring to a friend or relative who prepared your returns for you as a favor? Even if that is the case, you cannot get to the account or tax files without the account and user ID that they used.
You can get copies of your tax returns from the IRS, or free transcripts.

Or you can pay the IRS $43 for an actual copy of your tax return
