I have been using the desktop version of Turbotax for more than 10 years. I started this year's return about a month ago, and noticed the prior year's return data is incorrect. This affects the carry over values for investments, taxes paid in 2020 for 2019 returns, and the tax summary and history. This has never happened before. Possibly it was caused by having multiple copies of my 2019 tax returns - one that I had started and abandoned, and one that I finally filed. Is there any way to correct this problem? Or do I have to start over again and redo my 2020 return?
