In 2019, I began using a personal computer I had for 100% business use in February of that year, so, when TurboTax asked "Have you used this item 100% for this business since you acquired it?" I answered No and selected that "I used this item for personal purposes before I started using it in this business." Then, I entered the date in February for "Date I started using it in this business" and calculated about 90% as my business use in 2019 (since January-February had been personal use) and entered that as my "Percentage of time I used this item for this business in 2019."
In 2020, I used this computer the whole year for business use 100%, so can I up the "Business %" use to 100% in the TurboTax entry for it? I would assume yes, but the TurboTax "Learn More" panel says this about the entry:
"The only time you should change any prior year asset information is if it does not accurately reflect the information in your prior year return, or if your business use drops to 50% or less."
Any knowledgeable guidance on this is appreciated!
