I thought that I had filed my 2017 tax returns for the IRS and California in February using TurboTax.. However in checking (still looking for my refunds!) I discovered I had not pulled the trigger to actually complete the process.
What do I do now? Just go ahead and complete the process or do I need to go back into the return and do anything to indicate I am filing late or ??
Simply complete the process now. If you are owed no refund, there is no late filing penalty. If you owed tax, the IRS will bill you for any penalty or interest owed on the tax due.
