From the circumstances you have described, you should be able to file with our TurboTax Basic Online product or, at most, TurboTax Deluxe Online or CD/download.
The most complex part of your return will be dealing with the liquidation of the SEP-IRA, and that only involves entering the information from a Form 1099-R and answering some questions about what you did with the disbursed funds.
Begin with our free filing method online, and you will be guided to upgrade, but do not accept a suggestion to upgrade beyond Deluxe. Or if you prefer desktop products, purchase Deluxe and work with it. If you have any questions as you work through it, you can always turn back to this community for advice.
