I am a partner in the LLC. This is a fairly large partnership and the tax basis is maintained. The issue is that we Converted to a C Corp January 1 2019, however TurboTax appears to offer only one option to report the 2018 as a final K1 by selecting to report as a Complete Disposition in Fully Taxable Transaction. My understanding is this is NOT a taxable event and therefore the Basis should not be entered on Form 8949 with Box F checked.
