Every year there are forms that may not be available at the start of filing season due to changes in tax laws, etc. It depends on what forms you need. See the following 2 tables:

There's
no hurry to file now. The IRS will not start processing returns until
January 23 (except for a few test returns the IRS will pull
early.). Any returns filed early will just sit on TurboTax servers
until then and cannot be retrieved if you notice something wrong. You'd
later have to file an amended return.
Of course, you must wait on any W-2's, 1099's, etc. to arrive first before filing.
And
starting this year, if you have EIC (earned income credit) or ACTC
(additional child tax credit), the IRS will not start releasing those
refunds until February 15.
