Hi, thank you for using Intuit TurboTax Community
S101 is the opening balance sheet for first year filing corporations. Therefore only those corporations filing for the first time complete s101. For all other corporations the s100 for the previous year will be the opening balance sheet for the next year; a s101 is not required every year.
In TurboTax the s101 does not post to, or from s125. The closing balance sheet 100 and s125 are required every year with the relevant information
Hope this helps
