@duncanjstacy Using the TurboTax Home & Business edition you should be able to click on Personal and then click on Other Tax Situations. Scroll to the bottom of the page and click on Done with Other. The next screen should be the one where you are asked about the stimulus payments.
The only way to delete the return is to delete the tax data file for the tax return. The tax data files and any saved PDF's of the returns are stored by default in the Documents directory in the TurboTax folder.
