Get your taxes done using TurboTax

There's a different question in TT for "When the business incorporated?". If what you say is true, then what is the difference between "When the business incorporated?" and "When business started?" (They are two separate questions in TT). I'm in the same situation, I incorporated on a date in 2019, have been doing development and research, haven't conducted any business yet, so I have a date down for "When the business incorporated" but I don't know what to put for "Date business began". On other tax related documents, we were able to state the date of inactivity through the end of the year, but this doesn't seem like an option in TT. Any advice is appreciated.
